Add assertion attributes to child object on profile (passport-saml#543)

[kriss1897]

This attributes are also mounted to profile directly in a non conflicting way.

Duplicate PR of: node-saml/passport-saml#593

This failed build on 16.x is also failing on master. Will check and raise a PR to fix

@cjbarth @zoellner The test in node v16 is failing due to a bug in npm which causes npm to break after running npm update. I checked around and found that there are two workarounds:

1. Re-install node after running npm update
2. Use yarn to run test script. Or can we also consider using yarn for the whole project?

How is this then working in passport-saml if it isn't working here in node-saml?

[kriss1897]

I tried running these commands in the same sequence with passport-saml's package.json on this repo, but still the command was failing for this repo and not for passport-saml.

@kriss1897 Do you have a link to the bug in npm?

[kriss1897]

No, I didn't see any open npm tickets regarding the same. I found some old ones and some stackoverflow threads. Try this: https://www.google.com/search?q=cannot+find+module+npmlog+after+npm+update

It seems that this has been fixed. Could we revert the change and try again?
